Description
CATO supplies Ethyl 1-phenylisoquinoline-3-carboxylate (CAS 81803-40-9), a certified reference material (molecular formula C18H15NO2, MW 277.32 g/mol) for analytical method development and quality control.
Structurally, Ethyl 1-phenylisoquinoline-3-carboxylate (C18H15NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 277.32 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 1-phenylisoquinoline-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
